The influence of wall orientation and exterior surface solar absorptivity on time lag and decrement factor in the Greek region

Kontoleon, K.J.; Eumorfopoulou, E.A. - In: Renewable Energy 33 (2008) 7, pp. 1652-1664

The aim of this study is to determine how time lag and decrement factor are affected by wall orientation and exterior surface solar absorptivity, for specific climatic conditions. Their influence forms a non-sinusoidal periodical forcing function that simulates suitably the outdoor temperature...

Optimal harvesting strategies for a multi-cycle and multi-pond shrimp operation: A practical network model

Yu, Run; Leung, PingSun - In: Mathematics and Computers in Simulation (MATCOM) 68 (2005) 4, pp. 339-354

In this paper, we introduce a network formulation of the optimal scheduling model for a multi-cycle and multi-pond shrimp operation grounded on the original optimal harvesting theory for a single production unit. The optimal schedule comprises the harvesting and restocking time that maximizes...

Linear models, smooth transition autoregressions, and neural networks for forecasting macroeconomic time series: A re-examination

Teräsvirta, Timo; van Dijk, Dick; Medeiros, Marcelo - Economics Institute for Research (SIR), … - 2004

In this paper we examine the forecast accuracy of linear autoregressive, smooth transition autoregressive (STAR), and neural network (NN) time series models for 47 monthly macroeconomic variables of the G7 economies. Unlike previous studies that typically consider multiple but fixed model...
